Question

我在我的项目中使用apache休息CXF和camel。有很多情况下，休息的请求URI的长度太长，并且在一定长度之后总是会因为HTTP操作失败而发生异常，如下所示与

所以有任何方法，我们可以在发送请求之前在头中显式传递length参数，或者用于设置请求URI的最大长度的任何其他配置。对于解决方法，我只是使用HttpConnection替换了camel调用，它工作正常，这意味着驼峰对请求的URI长度有一些限制。

我将请求放在link

骆驼代码：

.choice()
                .when(header(ReservationConstant.CALL_ENDECA_FOR_LAR_FACETS).isEqualTo(Boolean.TRUE))
                .setHeader(Exchange.HTTP_METHOD, constant(org.apache.camel.component.http4.HttpMethods.GET))
                .setHeader(Exchange.HTTP_PATH, constant(ReservationConstant.ENDECA_GUIDED_SEARCH_SERVICE))
                .setBody(simple(StringUtils.EMPTY))
                //.to("cxfrs:bean:endecaLocationKeyRSClient?throwExceptionOnFailure=false")
                .to("{{service.endeca.location.dimension.rest}}")
                //.process(endecaFacetProcessor)
                .bean(EndecaResponseBuilder.class, "getEndecaResponseForLARFacets")
                .end()

问题似乎不是因为URI太长，而是由于我删除该标头后，请求中的其中一个标头过大的事实

通过apache GET进行HTTP操作当Rest请求URI太长时，Camel会失败
